The illustration depicts a technical drawing by Leonardo da Vinci of a multi-directional lantern or projector. It shows a central cylindrical lamp containing a candle, with several tubes radiating outward. Each tube ends in a stylized hand holding a flame, demonstrating Leonardo's early conceptualization of optics and light distribution.
